Im doing some research, can anyone tell me what frequencies does “texting” from a cell phone use ?
For example, the FCC is trying to find out how the various signal jammers can be used in a controllable way to give citizens the ability to block annoying phone calls with mobile phone jammers, but in case of emergency, the 911 can be called. on time. It was really a surprise to me that FCC started this attempt and I hope it will succeed because, despite this, it is only the beginning, but it is rather promising for me.
But there is another opposite situation with the manufacturers of tracking devices. They also learned about the use of GPS jammers on the Internet and decided to thwart GPS jammers and create new types of tracking devices. Here is an example of how they do it.
The 3G and 4G are totally different. To be branded as a 3G a communication system has to provide at least 200kbit/s data transmission speed. To branded as a 4G the same system has to provide data transfer speed up to 100 mbit/s for mobile users and up to 1 gbit/s for stationary users.
If you need the 4G standard – the frequencies are 2345~2400 MHz or 2.3 – 2,4 GHz. You may find more info on modern tendencies in 3G/4G standards development on our blog powered by Jammer-Store.
